Wu Jincheng was born in 1983, in Chazhai Village, Heku Town, Xiangxi Tujia and Miao Autonomous Region, and graduated from Hunan First Normal University in July 2007. After graduation, I want to be a special post teacher in Fenghuang County, Xiangxi, Hunan Province. Because it was not time to register, he first returned to his hometown, Chazhai Village, Heku Town. I didn't expect to hear that all the teachers in the small village were transferred back to the town to teach. Teacher Wu said that the river reservoir means a hillside without roads in Miao language, indicating that it is remote and poor, and the teachers outside have changed one after another and will not stay long. Seeing that the children can't go to school in the new semester, Wu Jincheng temporarily served as a substitute teacher, but I didn't expect this to delay the opportunity to be a teacher in Siheyuan. Because special post teachers only recruit fresh graduates, Wu Jincheng lost the opportunity to edit. A teacher who is editing needs a salary of about 2,000 yuan a month, while a substitute teacher only earns 840 yuan a month.
